摘要
针对工业园区电化学储能调度中普遍不关注储能寿命折损的问题,该文建立了考虑电池寿命损耗的工业园区电化学储能调度优化模型.该模型采用一种基于放电深度的电池储能寿命损耗成本计算方法建立储能折算成本模型并通过分段线性化提升模型求解速度.此外,对大容量储能系统中的各台设备独立建模以提升调度的精度和灵活性.进一步地,在调度目标中加入荷电状态(state of charge,SOC)健康评价函数以延长电池寿命折损并优化储能设备间的协调出力.最后,通过算例验证了所提模型的有效性和经济性.
Abstract
The life loss of energy storage batteries is often ignored when the economical dispatch optimization is carried out for industrial parks,for this reason,an economical dispatch model considering the life loss of energy storage batteries is established for industrial parks in this paper.In this model,a method based on discharge depth is used to calculate the energy storage life loss cost of the battery,and the piecewise linearization is used to improve the solving speed of the dispatch optimization problem.In addition,each equipment in the large capacity energy storage system is modeled independently to improve the precision and flexibility of the dispatch.Furthermore,the State of Charge(SOC)health evaluation function is added to the dispatch objective to prolong the battery life and optimize the coordination of the energy storage devices.Finally,the validity and economy of the proposed model are verified with a simulative example.
